Covid booster shots important to stop the infection, finds English study
Scientists urged eligible people to undergo Covid booster vaccinations after a major poll in England found evidence of “breakthrough infections” more than three months after full vaccination.
Researchers at Imperial College London analyzed more than 100,000 swabs from a random sample of the population and found that Covid infection rates were three to four times higher among unvaccinated people than those who had received two. strokes.
But while full vaccination substantially reduced infection rates, from 1.76 percent in the unvaccinated to 0.35 percent in the three months after the second dose, infection rates increased again to 0.55 percent from three. six months after the second shot.
The finding suggests that protection against infection, with or without symptoms, begins to decline several months after full vaccination, although other studies show that vaccine protection against hospitalization and death is much more robust.
“The possible increase in breakthrough infections over time reinforces the need for a recall program,” said Paul Elliott, head of the React study and professor of epidemiology and public health medicine at Imperial. “It is an incentive for people to receive the booster dose when it becomes available,” added Prof Christl Donnelly, a statistical epidemiologist on the study. The results came as new Covid cases in the UK rose to 42,776, the highest recorded since the end of July.
